Hi all, this is my first post in this forum in avery long time. I have been out of the hobby for about two years and decided to make a come back. At any rate, I decided to do a SPS/Clam/zoa tank.
So here is the issue, I added some frags SPS from a friends tank about 4 weeks ago...all dead with in a week. Their tissue sloughed away. two weeks went by and I bought a frag from a LFS, It's showing signs of tip burn and I have had it for about 3 weeks. I bought another 4 frags from a LFS (Idaho Grape Cap, Orange Cap, Leng Sy Cap, and a green slimer) The caps are doing ok (Idaho grape is starting to show tissue slough). The green slimer is starting to turn white at the base and start to have some of the tips turn white.
The clam looks great, but the a few of my Zoas have closed up and appeared to have died.
The local reef group I am in thinks that my Alk is the issue, but I am looking for some direction as far as where to start. Here are my tank parameters .
Tank is a bare bottom 120 gallon with 40 gallon sump.
Skimmer: Deltec AP702
CA reactor: Geo 612 (not in use)
Running Phosban and Activated carbon 24/7
Lighting: 2x250 watt DE Hamilton 14k MH with Lumen Bright reflectors and 2 54watt T5 actinic for supplementation
Circulation: 2X Tunze 6100s on a Neptune Aquasurf
Tank has been running for 3.5-4 months.
waterparameters :
Temp: 79-79.3
pH: 8.11-8.23
Spec. Grav: 1.026
dKH: 12 (4.29 meq/L)
Calcium (460-480)
Mag: 1140
PO4: 0 (Undetectable)
Nitrate: 0 (Undetectable)
Ammonia: 0 (Undetectable)
Topoff/Make up TDS: 0-1
Salt used for water changes is half Instant Ocean half Oceanic. Last water change was done yesterday at the advice of my local forum. I did 25% in hopes of getting the dKH reduced (my tank was at 12)...the dKH remained the same, 12.
I'm trying to solve the mystery that is causing things to die off.
Thanks!
